Benefits of technology

[0012] The information display device can be configured such that the device superimposes, for example, shooting information and focus points on a display screen.

Problems solved by technology

However, the camera described in Japanese Patent Laid-Open No. 2000-165730 is not to display shooting information and a subject image at a time on the screen of a display device.
On the other hand, when a finder screen is monitored through another image pickup device as described in the U.S. Pat. No. 4,704,022, there may be cases where the brightness of the display in the viewfinder does not fit the brightness of the subject.

Embodiment Construction

[0026] A preferred embodiment of the invention is described below with reference to the accompanying drawings.

[0027]FIG. 1 is an outline perspective view showing the structure of a single-lens reflex digital camera to which a finder device according to a preferred embodiment of the present invention is applied.

[0028] In FIG. 1, the single-lens reflex digital camera (hereinafter simply called the “camera”) 1 consists principally of an interchangeable lens barrel 10 and a camera body 30. In this structure, a desired lens barrel 10 is removably mounted on the front of the camera body 30.

[0029] A shutter button 31, a mode dial 32, a power switch lever 33, a control dial 34, etc. are provided on the top face of the camera body 30.

[0030] The shutter button 31 is to perform shooting preparation and exposure operations. The shutter button 31 consists of two-step switches, namely a first shutter release switch and a second shutter release switch. When the shutter button 31 is pressed hal...

Abstract

The present invention discloses a finder device and camera including the finder device having an information display device arranged near a mat screen on which a subject image is formed, and an imaging device for acquiring a finder image including the subject image on the mat screen. In this structure, the operation of the information display device is stopped in response to the imaging operation of the imaging device. This can prevent the subject image and the image displayed by the information display device from being difficult to see due to the difference between the brightness of the image on the mat screen and the brightness of the information display device. The information display device can be configured such that it superimposes, for example, shooting information and focus points on the image.

Description

CROSS-REFERENCE TO RELATED APPLICATION [0001] This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2005-160,622, filed on May 31, 2005, the entire contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a finder device. More particularly, the present invention relates to the improvement of a finder device in a digital camera capable of displaying on a display screen both an image being viewed and an image being shot. [0004] 2. Description of the Related Art [0005] Digital cameras are commonly known, which form an optical image of a subject on an image pickup device from light coming from the subject and passing through a photographing optical system, photoelectrically convert the optical image into electric image signals through the image pickup device, and display the resulting image on the screen of an image display device, su...
